Read somewhere, most likely on a thread here that some of the Tacoma's are are being shipped with low levels on the 6 speed automatics and to have dealership check it.
Tell the to use the "real check", not some automated system.
Is that something the owner can do?
If I take it to the dealer is there a way to followup to be sure he used to proper procedure to do so IF I can't just do it myself

There is a way to do it yourself, but with the sealed system it is a PITA. An immediate giveaway they didn't check manually is if they're done in just a few hours - because it needs to cool off completely before they even begin, like 4 hours just to sit, then do the check which might take an hour or so. Expect it to be there overnight or half the day at least. Because mine was low I wrote Toyota and got a 6 year 100k mile bumper to bumper warranty for free.

You bring the trans up to normal operating temp. On level ground there is a plug on the bottom of the transmission pan remove plug trans fluid should drip out. The manual says it should be at normal temp............

I thought the tranny had to be at 130 degrees or something like that as well.

Interesting, so fluid will just drip out of the bottom of the pan if all is well?

Can ya tell I am used to manuals?

They have to keep your rig over night to check it. The fluid needs to settle in the transmission. Toyota will give you a rental car while you wait.

Mine had it.

Louis,

Do you recall if the concern was over Mexican-assembled, Texas-assembled, or both?

I think the original posting was here on 24 Hour and I don't think it mentioned assembly location.
One answer was so detailed I am sure whoever they are, that they can shed some light on the issue.
I am still dumbfounded at pulling a plug on the pan and only expecting a drip (maybe the dip on a plugged system is like changing elements on a water heater)

I wonder if they will really check it or just tell me "it's all good", that is why I wondered if it was a owner project or dealer only.
Also trying to avoid two trips into town t take it in and go get it.

Guess I will crawl under there and see if there is any thread locker or tamper marking paint before I decide whether it do it myself.

Friends daughter had a BMW with a sealed engine oil system. Engine was very, very low on oil and it blew up. Wouldn’t own a vehicle without an oil dipstick....

Changed the trans fluid on a pair of 2012 Tacomas when I was on the east coast last year...

pulled the drain plug and let them drain out...poured the fluid in a milk jug to see how much I drained out
of each.. exactly a gallon...

to fill it, I pulled the top line to the trans oil cooler... with a small funnel, slowly poured in the correct amount
of replacement fluid...meeting Toyota T 1, T2 T4 and WS specs...

dealer wanted $400 per vehicle...me doing it saved my wife's g/f and son..$800 and cost $42 in 2 gallons of fluid.

Did you do filter also?
